Hi,I am trying to migrate my project (custom board using stm32mp153a and 256MB mem) from 4.1.0 to 5.0.0 but I am getting a panic when booting u-boot:Board: MBfdd8 Var2.15 Rev.B-14 DRAM: 256 MiB E/TC:0 tzc_it_handler:79 TZC permission failure E/TC:...

I am trying to migrate from ecosystem 4.1.0 to 5.0.0 however after getting all the device trees to compile and build plus a new image I am encountering a Panic in optee. The problem is that it just says Panic and I can't tell based on the debug print...

Is there a walk-through or example of how to setup secure boot using a custom device tree?As a side note, the following page returns "Permission Error", is that expected behaviour?https://wiki.st.com/stm32mpu/wiki/STM32MP15_secure_boot

I am trying to configure a DMA stream to capture the RX channel of a UART core on the m4, however, I get very undesirable behaviour.I am trying to set up a circular rx buffer that is of size 10 since the data coming back is of multiples of 5. Unfortu...

Is HAL_UARTEx_ReceiveToIdle_DMA supported on STM32MP15 products? If so is there an example for using it?

It changes the location of the optee in memory so that it is inside the 256MB

I am glad it helped at least one more person.

the issue was resolved but I don't remember the resolution

@Kevin HUBERthe issue had nothing to do with the toolchain but with the fact that RNG1 was not assigned to the secure core in CubeMX.

In the end, these are the settings that worked for me (a board with 256MB of memory): memory@c0000000 { device_type = "memory"; reg = <0xc0000000 0x10000000>; /* USER CODE BEGIN memory */ ...

Is there any documentation for configuring UART RX DMA in circular mode properly?
